This invention relates to the packaging for distribution of safety razorblades and consists in a novel package of blades securely protectedagainst becoming dulled or rusted up to the time 6 that they areactually presented to the razor by the user. The invention includeswithin its scope the novel protected blade herein shown as one componentpart of the package of my invention.

In handling safety razor blades under commer- 10 cial conditions ofdistribution and in the more or less casual handling by the user theextremely fine keen edge of the blade is likely to become dulled bybeing brought into contact with its wrapping or other objects before theblade can be actually clamped in its shaving position in the razor. Onthis account the best and most skillful efforts of the manufacturer insharpening blades are often brought to naught because of the difficultyof preserving intact the very fragile and delicate structure of a bladeedge which has been brought ta the keenest possible shaving condition.

With these conditions in view an important object of the presentinvention is to provide a novel package of protected blades in whicheach blade is enclosed between cover sheets projecting outside itscutting edge and protecting it from direct contact until such time asthe blade has actually been presented in its shaving position in thesafety razor by the user.

I have discovered that such a protective cover may be made to adhere toone or both surfaces of a safety razor blade in a clinging or slippingmanner of engagement so that it may be readily removed by being drawn orslipped off the blade. Preferably and as herein shown each blade isprovided with a protective cover sheet secured to its opposite surfacesin edge-free manner, that is to say, with the edges of the sheets inregistration with each other but not attached to each other opposite tothe cutting edges of the blade. The cover sheets thus employed toprotect the blades are then bound together or fastened at one end inbook form, each book or package comprising flve or six or more protectedblades.

The package of my invention is particularly adapted for thin flexibleblades internally apertured to receive the blade-positioning projectionsof a safety razor. The protective cover sheets are accordinglylongitudinally slotted in registration with the apertures of the bladewhich they enclose. Each of the leaves, moreover, may be transverselyscored or otherwise weakened so that it may be readily torn out of. thebook by the user and in accordance with another feature of my inventionthe weakened line of each leaf is so located as to intersect the slottherein and preferably at a point adjacent to or coincide with the inneredge of the slot, that is the edge of the slot nearest the binding ofthe package. An advantage of this construction is that when a leaf istorn from the package on the scored line only one end of the slot in theleaf is opened. In other words, the protective cover sheet which may beoriginally rectangular in form and some,- what longer than the blade is,by tearing off the sheet, converted into a U-shaped configuration. Itfollows, therefore, that the blade thus protected may be placed by theuser in his safety razor with the blade-locating projections thereofextending into the aperture of the blade. The dimensions of the slot inthe cover sheet, however, are such as to clear the blade-locatingprojections so that the cover sheet is free to be drawn ofl from theblade in edgewise direction while the latter is held positively in placein the razor. It will be noted that the sharp edges of the blade havebeen protected until after the blade has been presented in its finallocation and is no longer liable to be damaged by contacting with itswrapping or with any part of the razor to the serious detriment of itskeenness. After the protected blade has been so located the cover sheetsmay be withdrawn easily and with no tendency whatever to pass across ordull the cutting edges of the blade.

These and other features of the invention will be best understood andappreciated from the following description of a preferred embodimentthereof, selected for purposes of illustration and shown in theaccompanying drawing, in which- Fig. 1 is a view in perspective of theblade package, showing its outer cover in raised position;

Fig. 2 is a view in perspective of a blade-containing leaf of thepackage as it appears when torn from the package;

Fig. 3 is a view in perspective .of a razor for use with the blade shownin Fig. 2 is designed;

Fig. 4 is a similar view showing a blade in position in the razor andits protective covering partially withdrawn; and

Fig. 5 is a modified form of blade package.

It will be understood that my invention is in no sense limited for usein connection with any specific type of safety razor blade, and that ther particular blade shown represents merely one safety razor blade ofwell-known commercial type. The blade I 0 is of thin flexible steel,sharpened at its opposite edges for cutting and having corner recessesdefining an elongated centrallythrough its free ends.

disposed unsharpened portion. The blade is internally apertured. beingprovided with a long slot l2 having spaced enlargements ofcharacteristic outline in its length and being designed to register withand fit upon the blade-locating projections of the razor in which it isto be used.

As shown in Figs. 1 and 2, each blade is en-: closed and protected in aleaf 14, each leaf comprises two sheets of thin waxed paper or the likeof the proper size and shape completely to envelop the blade and toextend in edgewise relation slightly beyond the cutting edges thereof,so as to act as a guard or fender therefor. The

sheets of each leaf, moreover, extend longitudinally a substantialdistance beyond the ends of the blade and are maintained temporarilyattached thereto in slipping engagement by spots I! of vaseline or thelike. The sheets of each leaf are provided with a longitudinal slot l6registeringwith the slot of the enclosed blade and preferably beingslightly wider so as to clear the blade-locating projections of thesafety razor when the protected blade is presented thereto.

The individual leaves, each with its enclosed blade, are bound into hookform and held to: gether by the staple fastener 20 which, as shown inFig. l, is inserted through one end of the stack, and assembled with theblade-containing leaves is an outer cover 22 of pasteboard or the likeupon which advertising matter may be advantageously displayed. The cover22 may comprise a single piece of cardboard folded upon itself andstapled Its outer folded end '23 is scored or perforated so that it maybe torn off by the user in unsealing the package.

Each leaf is made of a single strip folded upon itself and is weakenedin a definite location as by being provided with a transverse scoredline "I which intersects the slot [6. As herein shown the scored line l8coincides substantially with the inner edge of the slot It. Thisfacilitates the removal of any individual leaf from the book by tearing,leaving the stub end of the leaf secured in the back of the book-likepackage. It will be noted that since the location of the scored line I8is such as to intersect the slot, the effect of tearing out one of theleaves is to open the inner end of the slot 16 and convert the leaf fromrectangular to U-shaped configuration.

Fig. 7 represents the package as unsealed by the removalof the end 23and Fig. 2 represents a leaf torn from the package,.the scored line l8defining the ends of the side portions of the U-shaped cover. In thiscondition the two sheets of the cover are maintained temporarily oryieldingly in place by spots of Vaseline I! or otherwise. The two sheetsof the leaf are separate and unconnected at their longitudinal edges andjoined by a fold at one end.

In Figs. 3 and 4 is shown one type of safety razor particularly adaptedto receive a protected blade of the character herein disclosed. This.

razor is the subject matter of my co-pending application Serial No.683,356 filed August 2, 1933, to which reference may be had for furtherdetails of construction, Briefly stated the razor comprises a guard 24'or blade-supporting member and cap sections 26 pivotally'mounted uponthe guard, cooperating therewith to flex the blade and maintain itclamped for shaving in a condition of transverse curvature. Thebladelocating projection of the razor in this case comprises alongitudinal rib 28 and upon this the slot l2 of the blade is adapted tofit and so maintain the blade accurately in proper position as to itsedge exposure for shaving. The razor is provided with a handle 30 and.with operating meohanism not herein shown for swinging the cap sectionsto and from blade clamping position.

In presenting a protected blade to the razor shown in Figs. 3 and 4 theuser has only to place the blade upon the guard 24 in the usual mannerwithout regard to the protective cover thereof, whereupon the rib 28enters the slot l2 and becomes effective to locate the blade and also tohold it against displacement in the razor. The blade may be thuspresented either end about as best suited to the convenience of theuser. Having thus located the blade the user has only to grasp theprojecting end or tab of the cover l4, and slip it endwise from theblade I0, as suggested in Fig. 4. The adhesive spots ll do not interferewith this operation but permit the cover to be conveniently withdrawnleaving the blade fully exposedand accurately located in shavingposition and without any possibility of objectionable contact havingbeen made with its cutting edges. Upon closing the cap sections 26 theassembled razor is ready for use. Meanwhile the remaining blades areretained safety in the package ready for removal and use as desired.

In Fig. 5 is shown an alternate form of package similar to that abovedescribed except that the protective covers 34 are formed with openendedslots 36. As herein shown they are bound together by a staple fastener38 in covers 40. In using this form of package there is no necessity fortearing out the respective leaves. Each leaf may be presented to thesafety razor and the blade Ill located upon the guard 24 in registrationwith the rib 28 and then the cover 34 removed from the blade by drawingthe leaf and package away from it in an endwise direction while theblade is so held.

While the package is herein shown as bound or fastened by a staple 20 itwill be apparent that any other suitable fastener may be employed, suchfor example as an eyelet or tubular rivet.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States is,-
